Saxon 70eb8193cb container/mts: wrote BytesForPTSInterval
This function will return the media between two provided PTS. Binary search has been used to
find the corresponding Frames to 'from' and 'to'.

Saxon 12c205d75f container/mts: wrote test for Clip.Bytes and generalised logic for generating frames into genFrames func 2019-06-13 18:12:17 +09:30
Saxon 1323cbcae3 container/mts: filled Clip.Bytes
writing Clip.Bytes required a change to the Clip type. The Clip type now possess a slice that
references the memory in which the Frames should reference for the media. Appropriate changes have
been made to Extract and TestExtract to accomidate this change.

Saxon 8f434e9703 container/mts: added payload_test.go and fixed bugs in Extract 2019-06-13 15:52:25 +09:30
Saxon b473451288 container/mts: added payload.go file with Extract function and types
payload.go has been added which will contain functionality for dealing with MTS
payloads. A function has been added called Extract, which will return a Clip. Clip
is a type representing a sequence of media frames ([]Frame). Type Frame has been
added which represents a media frame. It provides fields to hold the media as
byte slice, PTS to hold the PES timestamp, an ID for identification of codec type
and finally the relevant Meta from the most recent PMT.

Saxon e4bce3bcb3 container/mts: added ExtractMeta function and testing
Added function to extract meta from first PMT found in a mpegts clip. This simply
wraps the logic we've used in vidrecord, i.e. Finding the PMT, converting to a
comcast gots psi.PSIBytesm, using HasDescriptor to get the meta descriptor, and
then mapping metadata. Also added testing.

Saxon 9af964cfc9 container/mts/meta: added GetAllAsMap function
This function is very similar to GetAll, except that is returns a map[string]string rather
than a [][2]string. It's become apparent that a map[string]string might be more useful in
some circumstances.
